changed: - ---- === Possible Mentors === *Hans-Christoph Steiner *Georg Holzmann *Ben Bogart === Description === Pd comes with a quite limited set of GUI objects. Some additional GUI externals exist (e.g. knob, iemgui, ...), but a more complete and easy to use library should be written to build fancy user interfaces. All GUI objects in pd are written with the cross-platform [http://www.tcl.tk/ Tcl/Tk] toolkit. The inspiration for new objects can come from similar programs (e.g. [http://www.cycling74.com/ "Max/MSP"]) and should be discussed with the mentors and at the mailing list. Furthermore all objects should be graph-on-parrent capable and cross-platform.
